Abstract: A system for evaluation of a sheathing behind a casing of a wellbore. One or more wave generators provide at least asymmetric lamb (AL) waves through a casing having an anisotropic property in a first mode of the system, and provide at least shear horizontal acoustic (SHA) waves through the casing in a second mode that is concurrent with the first mode. A receiver receives indications associated with the SHA waves and the AL waves. At least one processor determines a quality of the sheathing behind the casing based in part on the indications associated with the SHA waves and the AL waves.

Abstract: A bone shortening osteotomy apparatus is configured to provide positive retention of the bone portions as the two cut bone portions are retracted. The apparatus utilizes a bone plate with a compression block detachable attached in a fixed position and a sled assembly that is slidably engaged with the bone plate. A jacking screw extends from the sled to the compression block to draw these two components together. K-wire barrels coupled to the sled converge to direct K-wires into bone. Sled guide pins extend between the sled and the compression block and preferably on opposing sides of the jacking screw to ensure straight movement of the sled toward the compression block. A cutting guide has guide slots for guiding a cutting implement through the bone. A slot wedge may be inserted through the guide slot after cutting the bone to stabilize the cutting guide and bone for subsequent cutting.

Abstract: An outer tubular is imaged by a pad assembly disposed within an inner tubular inserted within the outer tubular. The pad assembly is in contact with the inner tubular, and includes an acoustic pressure source, a backing mounted to a side of the acoustic pressure source, and an intervening layer between the acoustic pressure source and inner tubular. Signals generated by the pad assembly propagate radially outward from the inner tubular and reflect from the outer tubular. The generated and reflected signals travel through a medium between the inner and outer tubulars. An estimate of the distance between the inner and outer tubulars is based on the time from generation of the signal to when the reflected signal is sensed.
